Froggatt played for non-league East Kirkby Colliery, before joining Notts County. He played four league games during the relegation season of 1963–64 and subsequent Fourth Division campaign in 1964–65. He dropped out of the Football League to work as a painter and decorator and play part-time for Ilkeston Town and Buxton, before joining Northern Premier League side Boston United in 1969 for a £500 fee. They finished third, two points short of the title, in 1969–70; fourth in 1970–71; second in 1971–72, two points behind champions Stafford Rangers; first in 1972–73 by a nine points margin; and first again in 1973–74 under manager Keith Jobling. He transferred to Third Division Colchester United in August 1974 for a £6,000 fee, joining former Boston strike partner Bobby Svarc and former Boston manager Jim Smith at Layer Road. He scored his first Football League goal on 24 August, in a 3–2 defeat by Blackburn Rovers at Ewood Park. He and Svarc continued their strike partnership, and Froggatt scored a hat-trick past Grimsby Town on 15 November, whilst Svarc also scored a brace. He also found the net against Aston Villa in a 2–1 defeat in the League Cup quarter-finals. He started every league game in 1974–75, scoring 18 goals in 54 games in all competitions; Svarc scored 25 to take their partnership to 43 goals for the season. Svarc and Smith left the club in summer 1975, leaving Froggatt behind at Colchester. The club were relegated under rookie manager Bobby Roberts, and Froggatt scored just five goals from 44 games in 1975–76; this left new signings Bobby Gough and Colin Garwood to pick up the slack. However Roberts led the "U's" to immediate promotion in 1976–77; Frogratt scored eight goals in 52 appearances, though again Garwood and Gough got the bulk of the goals. He added four goals in 34 games in 1977–78 to take his tally for Colchester to 35 goals in 184 games in league and cup competitions. He was signed by Port Vale manager Bobby Smith for £10,000 in February 1978. Fifteen seconds into his Vale debut; a 4–0 win over Exeter City on 8 February 1978 at Vale Park, and he had scored his first goal for the club. Despite this, he only scored two more goals in eleven further league games in 1977–78, as the "Valiants" were relegated into the basement division. He then lost his first-team place to Ken Beamish and Bernie Wright, and after three appearances under new manager Dennis Butler in 1978–79, Froggatt was sold on to Northampton Town for £8,000 in September 1978. He scored three times for the struggling "Cobblers", before returning to Boston United, where he was made assistant manager.
